To estimate the turnovers of structural proteins of muscle, their relative rates of incorporation of five radioactive amino acids, glycine, leucine, valine, lysine, and alanine, were determined. The ratio of the turnover rates of M-protein (prepared by the method of Masaki and Takaiti (6)): troponin : tropomyosin : α-actinin: myosin : 10S-actinin : actin was approximately 7 : 6.5 : 3.3 : 3 : 2.5 : 1.7 : 1.
